  • The information is stored in the DWEPMA database on the data warehouse server.
  • The formulary is based on the First Databank standard.
    • The version in use is not the latest version.
    • The latest version is in test, but there have been problems.
    • It contains the same drugs multiple times for different manufacturers.
  • The prescription data does not always contain all the information (dosage, route, frequency, duration) as this may be added by the person who administers the drug.
  • Once created, prescriptions are never altered.
    • Incorrect prescriptions are stopped and a new prescription is issued.

Mapping

  • Depending on how closely the formulary sticks to the First Databank National Drug Data File (NDDF), it may be possible to use the RxNorm standard as an ontology or as a way to map the codes to SNOMEDCT.
  • Dosage, route, frequency, duration can be stored in i2b2 as modifiers. This would require i2b2 to updated version 1.6.
  • Another possibility is to user the National Centre for Bio-Ontology (NCBO) tools. Click Mappings tab and select 'National Drug Data File' from the options to show all the NDDF mappings, which contains a link to a mapping for SNOMED.
  • Also investigate First Databank to use SNOWMED CT article.
